Abstract: Encoding and decoding method and apparatus are dis­
closed including a decoder for decoding a stream of encoded digital 
data words which have been encoded by an encoder using var­
iable length code words in which the code words comprise a single 
group of 0 bits followed by a single group of 1 bits. The 0 bits and 1 
bits are separately counted (46), and the combined counts are used 
to address a read only memory (54) containing the decoded digital 
data words. The decoded digital data word is read out from the ad­
dressed memory location. Also disclosed in an AND gate array (70) 
of rows and columns of AND gates (90-1 etc.), in which the num­
ber of 0s in the code word determines which row is energized, and 
the number of 1s in the code word determines which column is ener­
gized. The energized AND gate is indicative of the decoded digital 
data word.

Abstract: The charging device for a refuse-collecting container, in particular for a refuse-collecting vehicle, comprises a filling trough situated between the side walls of the charging device, a compression-blade arrangement which can be swivelled back and forth above the bottom of the trough and is connected fixedly in terms of rotation to a shaft passing through the two ends of the side walls, and at least one swivel drive for the compression-blade arrangement, which engages on the shaft, is arranged on the outside of the side wall and has at least one hydraulic cylinder, as swivel-actuating member, which engages on the shaft by means of transmission elements. The intention is to develop the charging device in such a way that its operation results in little wear and maintenance, and that tolerances and deformations due to manufacture, assembly and operation have no effect on the functional reliability, so that said device is adapted in a trouble-free manner to the rough working conditions over a long service life. For this purpose, the swivel drive (11, 11a) has a block-like supporting part (12, 12a). On this is fixed the hydraulic cylinder (16, 16a) and in this is mounted the shaft (21) and the transmission elements are housed on the inside. The supporting part (12, 12a), together with a shaft (21) which passes bearing-free through the side wall (5), is held next to the side wall (5) by means of at least two articulated bearings (22, 24; 15, 27, 26, 25) located on frame parts (6, 7) which at least partially encompass the side wall (5). In this design, it is advantageous for virtually all the components loaded with the reaction forces from the movement of the blade arrangement to be mounted and supported in and on the supporting part, which in turn is held directly on the frame parts. The supporting parts in turn can be designed with little outlay in terms of construction in such a way that the loadings occurring are absorbed satisfactorily. <IMAGE>

Abstract: A method for determining level of molten metal in the input of a continuous metal casting machine (15) having at least one endless, flexible, revolving casting belt (12,14) with a surface which engages the molten metal (16) to be cast and a reverse, cooled sur­face along which is directed high velocity liquid coolant includes the steps of predetermining the desired range of positions of the molten metal pool and positioning at least seven heat-sensing transducers (1a-10a,1b-10b) in bearing contact with the moving reverse belt surface (12a,14a) and spaced in upstream-downstream relationship relative to belt travel spanning the desired pool levels. A predetermined temperature threshold is set, some­what above coolant temperature and the output signals of the transducer sensors are scanned regarding their output signals indi­cative of temperatures of the moving reverse belt surface. Position of the molten pool is determined using temperature interpolation between any successive pair of upstream-downstream spaced sensors, which follows confirmation that two succeeding   downstream sensors are at temperature levels exceeding thresh­old temperature. The method accordingly provides high resolu­tion for determining pool position, and verifies the determined position by utilizing full-strength signals from two succeeding downstream sensors. In addition, dual sensors are used at each position spanning the desired range of molten metal pool levels to provide redundancy, wherein only the higher temperature of each pair of sensors at a station is utilized.

Abstract: For the fabrication of semiconductor chips with an increasing number of electrical elements it is necessary that the geometry of the elements becomes smaller and smaller. For that purpose, lithographic techniques have been developed using x-rays, electron or ion beams. Especially for particle beams, self-supporting masks are stringent with the consequence that it is not possible to fabricate e.g. a ring-shaped structure with one mask. This so-called mask stencil problem is solved by exposing the chip with two complementary masks. The present application relates to a method for automatically splitting one layout into two complementary patterns for said two masks. The method determines all corners of said layout which extend into a hole representing area of said masks. A stability criterion is carried out for said corners, with the consequence that only instable corners are used for cutting said hole representing area into sections. Subsequently said sections are distributed onto said two patterns alternatively.
